Unfortunately the guest-tools-0.3 drivers seem to have introduced a new problem that is even worse than what I experienced before, they crash the Windows 7 guest images. I have had multiple crashes so far and these happen when I am not specifically doing anything in the guest (I try to avoid saying they are idle, as I never quite know what Windows is doing behind the scenes). I estimate that they crash after half an hour or so. The offending driver appears to be vioser.sys as shown by the very limited information (a screenshot of the BSOD) I managed to capture: *** STOP: 0x0000008E (0xC0000005, 0x8B98C037, 0x8A40BACC, 0x00000000) *** vioser.sys - Address 8B98C037 base at 8B988000, Datestamp 50b73b6d Please let me know if there is anything I can do to help. </pre> </blockquote> </blockquote> Erik, That may be a viable, although undesirable, workaround for disk IO, but in my case the BSOD's appear to be caused by vioser.sys, i.e. the serial driver. I believe this driver is used for communication between the host and guest and an important part to make cut/paste work. There really is no alternative. My motivation for writing about this here is not so much to get a workaround (although that would be very nice), but rather to make a minuscule contribution to improving the project. So again, if there is anything I can do to help debug this, please do not hesitate to ask. Cheers, Han </body> </html>
